Using Readyboost on X31

[rckrchrdsn]

I know the X31 is USB 2 compliant, but when I try to use a Titanium Cruzer 4Gb which is supposed to support ReadyBoost, Vista says the device is not compliant. I am wondering if this is a legacy USB port issue or a driver issue. The Flash works fine on desktop.

Check your driver, you should have two USB Host Controllers, low speed 1.1 and high speed 2.0 listed in your devices.

The SanDisk Cruiser Titanium is listed as ReadyBoost capable.

Yeah, that's why I got the TiCruzer. But it is nice to have another person verify it when something is misfiring.

I had not even thought to check which hub it was considered to be on. I assumed it would come up under the USB, but why assume? I will check it out. I have run the Updater 3.0 from the Lenovo site and I am pretty sure all my drivers are up-to-date.

Thanks

Platforms designed to run Vista don't have this problem. Platforms that are pre Vista not so lucky. Might want to check with whomever designed your USB controller and see if they have a driver for Vista. It's worth a look.

What would be really cool is ReadyBoost for the graphics.....

Well, ReadyBoost compliance is actually kinda sketchy. Basically what ReadyBoost does is to test the read/write speeds on your device three times, take the average, and if it hits a certain threshold, it will flag it as okay for ReadyBoost and allow Vista to use it.

The problem is that due to the way many thumb drives are designed, it can have a small chunk of really fast memory followed by a bunch of not-so-fast memory (mostly done to save on cost). The idea is that when Microsoft originally published the ReadyBoost compliance guidelines for Vista many manufacturers tweaked their thumb drives to show a passing grade (Especially the cheap generic ones from China) - and when Vista revised the test, alot of the thumb drives either fails the test, or barely pass it. My suggeston? Look at the System Event viewer. When ReadyBoost in Vista tests your devices it'll usually report the read/write speed to the event viewer. See if the device means the Vista criteria for those speeds. It is in fact possible for 3 tests to run up 3 different values due to the interleave of fast/slow memory. If it fails the ReadyBoost test, run it again immediately. With luck the caching algorithm on the flash drive will kick in and squeak the drive past the ReadyBoost Threshold.
